Two dimension numerical study of resonant free surface motion in the gap between two fixed vessels

    Abstract

    The study focuses on wave induced oscillations of flow inside a
    narrow gap formed by two identical boxes arranged side-by-side.
    The problem to be analysed is that of gap resonance behaviours
    with different gap entrance shapes, incident wave steepness and
    model scales. We employ the open-source CFD package
    OpenFOAM and restrict the problem to two-dimensional
    geometry and fixed boxes. It is found that as wave steepness
    increases, the frequency corresponding to the maximum response
    of the fluid in the gap will shift to higher frequency and the
    response curve closely resembles that of a Duffing oscillator with
    a hardening spring (as also reported by Vinje, 1991), depending
    on different entrance shapes. The results also show that a
    pronounced scaling effect is more evident for cases with rounded
    corners compared with counterparts with square corners or bilge
    keels. This may have implications for drawing conclusions
    applicable to full scale from wave tank tests.
